Optional arguments

[eaglejon67]

This is my constructor:

Object(arg1 = default1, arg2 = default2, arg3 = default3)

Is there a way to initialize this with only specifying arg1 and arg3, and having arg2 stay as the default2?

I don't believe so, no.
BUT, you could make the object have if structures inside to sort out the data and maybe... just maybe... make it re-arrange them(sort of(hypothetically speaking)).

You'd have to change the order of parameters. The default parameter/s must always be the last one/s.

That would be a really good addition to C++0x to allow the call Object(10, default, -2);... I think

Thank you.

You could use constructor overloading for this.....but if you have all the three parameters with the same type then you could use templatization to solve the purpose
